 Post subject: Any way to avoid ANSI style joins?

I'm using JPA/Hibernate against an older (7.30) Informix database. I'm using the informix dialect. I'm getting syntax errors when Hibernate generates ANSI style joins like this...
Code:
SELECT blah
FROM foo LEFT OUTER JOIN bar ON foo_id = bar_id


It appears that Informix 7.30 doesn't support ANSI style joins and the SQL needs to look like this...

Code:
SELECT blah
FROM foo, bar
WHERE foo_id = bar_id


Is there anyway to get Hibernate using the Informix dialect to use "old style" joins?

Thanks!

I'm still struggling with this issue. Our version of Informix (7.30) doesn't support ANSI style joins. We have over 1,500 servers across the globe running this database server. So a quick upgrade is not feasible although we are looking at it as a long term solution.

I even looked through the Dialect classes to see if there was an easy change I could make to get it to use "old style" joins and I didn't see anything.

If anyone has any suggestions I'd love to hear them.
